Because some of the wounds had linear components earlier described by Harris, Catellier said the "first thing that comes to mind is that these may be patterned, and a common instrument that produces this is the back of a claw hammer."
McDaniel had significant injuries to his neck. Several of the abrasions were adjacent to tears of the skin, she said.
"Contact [with the neck] included significant force," she said.
The highway bone was fractured and many of the layers of muscle had hemorrhaged. The thyroid cartilage was also fractured, "so there was significant blunt force injury here," she said.
If only pressure was applied to the neck, then "considerable friction force" had to have accompanied it to cause the skin to tear, she said.
"Most likely there was at least a combination of blows to the neck," she said.
The official cause of death was "blunt force injuries of the head and neck with probably a component of asphyxia due to strangulation," she said.
She also said there was likely "some degree of struggle."
Pollard's girlfriend speaks, leads police to Promise Center
On March 15, 2012, law enforcement sat down with Amanda Collins, Pollard's girlfriend. She told investigators that Pollard had come home the night of March 11, 2012, in a taxi cab. She also said Pollard had arrived in different clothes than when he had left.
Pollard was picked up in the 200 block of Commercial Street, one street south of East Main Street.
So officers began a "sweep" of that block, Harris said, and began pulling doors to see if they would open. One did, the back entrance to the Promise Center.
During a search of the center, officers discovered pornographic DVDs and magazines matching those found at Cinema X. Earlier that day, officers found Pollard at Ottumwa Regional Health Center with a backpack containing pornographic DVDs.
